'8-G!aims; (Cl. 98-94) "This invention relates to a bracket and panel assembly for use in mounting a ventilatorjin an opening inia wall or elsewhere, asj'for example, a ventilator adapted to,be mounted in a window opening. IIAn object of, this invention is, to provide a bracketadapte'd to support a window ventilator by interlocking -.,partsof the window ventilator in such a manner that the window ventilator may be easilyv mounted in a,window,-as for example in a. windowof the. double hung sash type, without the use of any otherfas't'ening device.

Another object of .this invention is to provide a pair offlbrackets simulating decorativewindow pane sections, cooperating with adjustablepanel m-rmbers also simulatingdecorative windowpane sections, the panel members being adjustable with respect to the brackets, so as tovaccommodate windows of various widths, the .panelsbeing selectedfromaplurality of sizes ofpanelsto prop,

- Inthedrawings, the reference characters 25) and 22 are2used to designatecthetwoopposed plate. members or panel brackets. .Each of these ba gage prnvlded-r;-with z apertured sears t24 i6o Hill driven by a motor I02 mounted upon the end adapted to overlap corresponding ears'of the ad jacentlbracket and adapted to receive bolts for holding thev brackets together, as shown inFigure 4. Each of the brackets is provided with vertically disposed ribs 26, simulating moldings. 'The brackets are also provided with horizontally disposed ribs 28, used in reenforcing the brackets and for presenting an ornamental appearance. Each bracket is provided with arcuate indentations formingopposed surfaces 39 and notches 32 and 34. The notch 34 in each bracket is subtended by a horizontal portion 36, used in -facilitating the insertion of the bracket upon the spacers 38 of the vent latin unit. The Walls of tho notches 32 form dihedral angles and are flared outwardly, as best shownin Figure 5, so as to be fixedly seated uponthe extensions or pro- ,ie-ctions 38 located between the .adjacent'hoops 39 of the fan assembly shownin Figure 5. The hoops 39' cooperate to form a housing for the fan member its forming the inner end of the fan assembly. A capping member I06 juxtaposed adjacent the margin of the deflecting m mber I08 closes the opposite end of the fan assembly. The fan assembly is more fully disclosed in the Welch appl cation for United States Letters Patent Serial No. 515,858, filed January 3,1944, for Plastic Ventilator Fan, now Patent 2,441,737 The notches32 and 34 cooperate with the extensions 38 to rigidly hold the fan assembly in positionon a window, as shown in Figure 4, the entire fan assembly being carr ed by the brackets 2i! and 22.

As best seen in Figures 5 and 6, the brackets 29 and 22 are provided along the lower edge with flanges it and t2, the flange 48 being smaller than the flange lz. Likewise, the brackets are provided along the upper edge with flanges M and 43, the flange it being smaller than the flange 46.

A chann l-like sheet metal member 58 terminates in a reentrant flange 53 overlapping the flange 4B and a second reentrant flange 52 overlapping the flange 4-2 and terminating in an upwardly directed flange 54. This flange extends in parallel relation to the outer surface of the brackets 26 and 22 and cooperates therewith to form channel'seats or recesses adapted to receive panels 56. These panels 56 extend beyond the brackets 2i! and 22, so as to close the opening of the window beyond the brackets. These panels 56 are selected from aplurality of panels or various dimensions, the selected panels having the desired width to close the openings" on the sides of the brackets Zn and. 22.

As best seen in Figure fl, achannel-li-kesheet mlv d eei a nseman fe s-mana e s?-' lation from the outer side of the brackets 20 and 22 and cooperating therewith to form a channel for the upper edge of the panel 56. An L-shaped bracket or clip 66 cooperates with a resilient clip 68 to engage the sides of the lower sash member 10. The L-shaped bracket 86 and the spring clip 68 are welded or otherwise se- 1 flanges for reenforcing the plate members and cured to member 60, so as to provide a rigid support for the upper edge of the brackets 28 and 22 and the'panels 56. The panel members '5 are provided with outwardly directed ribs 74 overhanging the flange 54, so as to prevent water and other precipitation from entering the channel portion formed'between the flange 54 and the corresponding bracket 2!] or 22.

' Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.

Having thus described my invention, I claim:
